I really don't think you mean that literally!
I mean, the Ada language standard does not require that "X := X + 1"
take less than 100 years to execute. Programmers _must_ trust that
language implementers make reasonably efficient choices. In fact,
in Ada, I write things like "X := X + 1" all the time, trusting that it
compiles into a single machine instruction, or close to that.
